Description
The utility model belongs to the particle that separates disperse from gas, and particularly a kind of liquid of using separates the combined apparatus of dispersed granules and pernicious gas as release agent with by gravity, inertia force, centrifugal force from gas.
For preventing that flue dust is to the pollution of atmospheric environment, the smoke dust discharge concentration and the sulfur dioxide (SO of last industry boiler
2) concentration of emission is restricted, and must not surpass state-set standard.When boiler uses the coal of sulfur content 1～3%, need carry out desulfurization to flue dust and handle.Existing desulfurating dust-removing equipment, wet type, half wet type are arranged, the branch of fountain and bubble type is arranged again in the wet type, fountain is that flue gas is introduced shower nozzle on spray equipment, the water distributor towards flue gas injection, utilize water to contact, the flue dust of washing in the flue gas, partially absorb the SO in the flue gas with flue gas
2Generally be behind existing cyclone dust collectors, the low group of configuration devulcanizer combines.Therefore, volume is bigger, and operation is complicated, and water consumption is big, costs an arm and a leg.The desulfurizer of the old boiler transformation usefulness that do not suit.Chinese patent " ZL93219645.4 smoke-melting type dust-removing desulfurating apparatus " provides the dust-removing desulfurating apparatus that is directly installed in the flue, the water-jet pipe promptly is installed in flue, is prepared alkaline desulfurizing agent, inject the water pump pressure pipe by chemicals feeder and mix with water, magnetization enters water sprayer and sprays.The structure more complicated.
The purpose of this utility model is, design and produce a kind of wet type desulfurizing dust collector, adopt whirlwind, inertia combined dust-eliminating mechanism, when the dust constaining air-flow rotates, the continuous blowdown water of boiler is sprayed into, under the pressure release and latent heat of vaporization effect of sewer, form the atomizing water curtain, make the water droplet particle fully contact, mix, condense and utilize the alkalescence of sewer with smoke particle, in and SO
2, CO
2Sour gas reaches desulfurization and dedusting.
Wet type desulfurizing dust collector of the present utility model, form by dedusting tube, cone, air inlet, air outlet, ash bucket, it is characterized in that: in the cyclone dust removal tube, be equiped with blinds inertial dust collection core pipe, the air inlet place is provided with the alkaline water spray equipment, the ash bucket place is provided with the auger conveyor deashing device, and the inwall of dedusting tube and cone is provided with corrosion-resistant lining cutting.
Blinds inertial dust collection core pipe is at core pipe middle part air deflector to be set, and air deflector is made of wheel shaft and radial flow deflector, and the flow deflector plane becomes 45 degree oblique angles with the water conservancy diversion wheel shaft; The air deflector below is provided with louvre blade in groups, and louvre blade length equals core pipe diameter length;
The alkaline water spray equipment is made of water inlet pipe, filter, flow controller and nozzle, and nozzle is arranged on the air inlet place of dedusting tube;
The auger conveyor deashing device is made of motor, decelerator, driving belt, auger, sprocket wheel, hand plunger, and the auger axis is horizontal, and hand plunger is located in the ash bucket, sprocket wheel and electric machine main shaft interlock;
Corrosion-resistant lining cutting is to draw in the net on the plate, and the acidproof cast stone concrete layer of casting is spread the sodium silicate mastic surface layer.
Operation principle of the present utility model and using method are, continuous blowdown system of boiler water is introduced water inlet pipe, spray by nozzle, because the pressure of sewer discharges and latent heat of vaporization effect, obtain good atomizing effect, form water curtain, water droplet particle and smoke particle are fully mixed, particularly micro dust particle there is higher capturing ability, thereby improves dust removing effects.When flue dust gas enters dedusting tube air inlet, when contacting with the alkaline water curtain of spray, SO
2, CO
2Sour gas by pH value more than 8, be the sewer neutralization of alkalescence.Then, ash-laden gas tangentially enters the dedusting tube from air inlet with helix, coarse dust is bigger because of centrifugal force, is thrown toward an inwall, with the outer vortex down current, fall in the ash bucket, fine dusts can be because of the inertia force effect near near the core pipe time, and collision is on shutter board, and rebounded around cylinder inboard wall, together drop in the ash bucket in company with coarse dust.The flue gas of dedusting and desulfurization, in air deflector, be forced to do inertia impact turnover, in the impact compress process, flue gas is separated once more with the dust-laden drop, and dust-containing liquid drops in the core inside pipe wall and confluxes, and enters ash bucket, start the motor of auger conveyor deashing device, dust is promptly removed by auger.The gas that purifies rises in the rotation of core inside pipe wall, enters atmosphere by air outlet.
The utility model has the advantages that: the deduster of cyclone dust removal and the combination of blinds inertial dust collection, the dual-use function that possesses whirlwind and inertial dust collection, ash-laden gas tangentially enters the deduster cylindrical shell from air inlet with helix, the efficiency of dust collection height, the pressure loss is little, the smoke treatment amount is big, under the bigger occasion of initial dust content, is very suitable as the first class purification of two-stage dedusting; In the cylindrical shell of a dedusting, realize dedusting, desulfurization double technique, at the flue entrance place, two nozzles are set, spray into boiler alkalescence continuous blowdown water to flue dust, because absorption liquid is forced rotary-atomizing, and higher hydrodynamic head is arranged, carry out gas, the solid, liquid three-phase fully contacts, the pH value of absorption liquid is higher than 8, can guarantee SO in the flue gas
2Removal efficiency with dust.Be furnished with mechanical automatic ash removing device, wet dust is exported automatically by auger conveyor, is convenient to bookkeeping, reduces secondary pollution.Through environmental administration's monitoring, efficiency of dust collection is more than 95%, and desulfuration efficiency can reach 40-60%.Occupation area of equipment is little, and ash discharge is half-dried, half wet condition need not be provided with sedimentation basin, and small investment is reliable, long service life.Be applicable to the supporting deduster of boiler, be specially adapted to the transformation in old boiler room.
